The Hôtel de Rambouillet, formerly the Hôtel de Pisani, was the Paris residence of Catherine de Vivonne, marquise de Rambouillet, who ran a renowned literary salon there from 1620 until 1648. It was situated on the west side of the rue Saint-Thomas-du-Louvre, just north of Marie de Rohan's Hôtel de Chevreuse, in a former quarter of Paris, located between the Louvre and Tuileries palaces, near the then much smaller Place du Carrousel, in the area of what was to become the Pavillon Turgot of the Louvre Museum.

Catherine de Vivonne, marquise de Rambouillet, known as Madame de Rambouillet, was a society hostess and a major figure in the literary history of 17th-century France.
